Heaven's Mirror

The video game "Eternal Sonata" has the flower known as "Heaven's Mirror." As explained by Polka to Frederic Chopin, these flowers stay in their buds by the day, absorbing sunlight, blooming in a spectacular light show at exactly 2 A.M. in the morning. (And, yes, this is rife with symbolism, as Chopin's time of death in the real world is 2 A.M.) She explains that the flowers also have another name: "Death Lights," for the flowers bloom in darkness and the dark brings death. She tells him what he chooses to call them is up to him.
